The 3RACING Cero Sport Fiber Glass Upper Deck, SAK-CS129/FG, provides a targeted increase in torsional stiffness to aid setup consistency. Fitted to the Cero Sport platform, it helps reduce transient chassis movement that can unsettle steering during quick direction changes.
Fiber glass offers a controlled stiffness profile that complements suspension tuning. It supports consistent roll and yaw response, enabling more predictable changes when adjusting springs, dampers, or anti-roll settings.
Install the deck using factory mounting points and verify that screw lengths do not compress or stress the fiber glass. Check interaction with servos, battery trays, and radio gear to maintain centre of gravity and component clearance.
Routine inspection of mount points and fasteners preserves the deck's contribution to handling. Replace any damaged fittings and re-torque screws after initial runs to lock in consistent performance.
